Inventor: MOORE WILLIAM THOMAS
IPC: H04N3/09
Filed: 1986-08-18
Abstract: A twin polygon thermal imager is provided with a compensation means for compensating for horizontal distortion in the image produced on a CRT. The distortion correction means applies an amount of correction which is determined, in each horizontal line, to compensate for the particular magnitude of the distortion in that line. The amount of correction needed is determined as a function of the angle between the rotational axis of the polygons and the particular facets thereof producing the particular video line. Compensation is achieved by adjusting the timing and the frequency at which digital video data is read-out from a signal store.

Abstract: In the process, the cooking liquor is burnt, the magnesium oxide and sulphur dioxide contained in the resulting combustion gases are extracted for the manufacture of magnesium monosulphite (MgSO3) and magnesium bisulphite (Mg(HSO3)2), a part of the MgSO3 is thermally cleaved and the resulting products are recovered. In order to free the hot process gas practically completely from fine MgO dust without significant cooling and thereby be sure of avoiding encrustation of parts of the plant during the subsequent cooling of the process gas, the hot process gas containing S02, MgO and H2O arising from the cleaving of the magnesium monosulphite is subjected to filtration by means of a random non-woven (5, 18) to separate the MgO dust and the non-woven is cleaned as necessary. The filter apparatus consists of a heat-resistant housing (1) and a filter element which can be inserted in the housing (1) in the stream of process gas to be filtered, the filter element being fitted with a random non-woven of high temperature-resistant, sintered metallic material, in particular made of stainless chromium-nickel steel or chromium-nickel-molybdenum steel, or with a ceramic non-woven, with cleaning devices being provided within the apparatus. <IMAGE>

Abstract: A shock wave source (1) comprises a decoupling membrane (7), which can be coupled fcr example to a patient (13) via the coupling body (11). The coupling body (11) consists of an elastic, dimensionally stable material (e.g. a solid hydrogel) with damp outside surfaces. In the coupling body (11) there is a shock wave sensor (15). The shock wave sensor (15) can be in the form of a small electrical pressure sensor, e.g. a piezoelectric sensor with PVDF film, or a (preferably optical) indicator, for example in the form of a thin lead sheet. An advantage of integrating the sensor (5) and the coupling body (11) in this way is that the functioning of the shock wave source (1) can be monitored during treatment of the patient (13). After maintenance or repair work, the use of the coupling body (11) permits simple, correct adjustment of the shock wave source (1) to its original operating data (e.g. position). <IMAGE>

Abstract: In order, in a refrigeration system with recuperation of the condensation heat, to counteract a reduction of the refrigerating capacity on changing over from cold production operation alone to simultaneous cold production and heat recuperation operation, the refrigerant condensate which accumulates is supercooled before its supply to the pressure relief member (18). To this end, a second heat exchanger (16) is used, which is connected on the refrigerant side after a first heat exchanger (14) which serves as liquefier. The active heat exchange surface of the second heat exchanger (16) is in this connection adapted to the respective operating state by means of accumulation of refrigerant condensate depending on the temperature level of the recuperated condensation heat, as a result of which simple regulation of this temperature level is simultaneously brought about. <IMAGE>

Abstract: A drive control for a vehicle such as a floor scrubber, a floor sweeper, a pallet truck or the like, operated by a person walking or riding on a sulky behind it, includes first and second drive motors each arranged to drive a vehicle wheel. Manual means are provided whereby an operator by manipulation of a control (14) may determine vehicle speed; forward and reverse direction; and turning right or left. A variable voltage (44) is responsive to the operator's movements for providing an electrical signal representative of the desired speed in either the forward or reverse direction. Other movements by the operator of the control (14) provide turning in the right or left direction. The means for detecting a turning control signal (52, 54) from the operator is effective to reduce the motor drive signal to the motor on the inside of the desired turn, from the level representative of the existing speed toward a no-speed level at a programmed rate. The control further includes a proximity reverse sensing means (68) effective to stop reverse movement of the vehicle upon sensing the presence of an operator closely adjacent the rear of the vehicle and for providing a short burst of forward movement of the vehicle upon such detection. The control further can provide signals to control operative functions of the controlled vehicle which may be affected by speed or direction of the vehicle.

Abstract: With electronic and printed picture display an adjustment is required so as to obtain a changed picture quality with the aid of a setting of a picture signal processing circuit subsequent to a picture quality observed. This adjustment is a calibration as it were of the picture signal channel for the picture display. Hereto the system comprises a picture pick-up device (CAM) such as a camera, a picture signal storage device (Dsc) in the form ofa disc, for example, and in a picture signal source (VPC) a playing device (VP) suitable for this disc, coupled to an electronic picture display device (Vmon) or still picture printer (Prt), respectively. During the adjusting operation a reference test pattern signal coming from a generator (Tst) is applied to the picture display device (Vmon) or printer (Prt), respectively, through a picture signal processing circuit (Proc). Subsequently, the pick-up device (CAM) picks up the picture displayed or the picture printed, respectively, and the picture signal obtained thus is stored in a storage device (Dsc). Then, this picture signal and the reference picture signal are compared in a signal comparing circuit (Comp). Adjusting data corresponding with the differences between these signals are stored in a memory (Mem) coupled to the circuit (Proc). Thus, with the electronic and printed picture display a video channel (V) as well as a printing channel (P) are adjusted. The two channels (V and P) are coupled by setting means (Adj. Proc), so that on account of the picture quality observed on the picture display device (Vmon) a changed picture quality of the printed picture of the (Prt) device is available.

Abstract: The invention relates to a digital filtering circuit for determining which value is in the k<th> position of an increasing or decreasing ordered sequence of n binary digital values received out of order by the filter. It is determined whether there are k or more than k zeroed high-order bits in the n high-order bits of the n values to be processed, and a possible modification of the other bits is deduced therefrom; then, the same determination is begun again on the bits of immediately lower rank, taking into account bits such as have or have not been modified; a modification is made again depending on the result of the new determination; and so on down to the lowest rank. The sought-after value is given in binary form by the signals representing the results of these successive tests. This filter is particularly suited to real-time filtering of television picture signals. <IMAGE>
